System for caracterizau00c7u00e7o materials via the identificau00c7u00e7o of changes occurring during thermal treatments on energy, high termosensu00cdvel constituent of the system, method of utilizau00c7u00e7o of same and their uses.This invention describes an apparatus and a system for characterization of materials through the identification of variau00e7u00e3es energy of said material during heat treatment.The system described in this invention uses a heat sensitive apparatus, in which the sample to be tested is subjected to a thermal flow until a condition close to balance; so the thermal response to be monitored and analysed.The present invention advantageously is instrumented to allow, a unit of data acquisition, monitoring, storage and simultaneous processing of all the data obtained, as well as the determination of the order of magnitude of the energies related to the phase shift of the materia Al, or the glass transition in a direct way and controlled.In this way, through increments minimum electric current and voltage of the system can be precisely the response curve of time temperature of samples subjected to heating or cooling.The system described in this invention can, therefore, be used for the determination of freezing point of substances, as well as to the order of magnitude of energy related to the phase change of the material or glass transition temperature.The thermal evaluation is important industrially and to science, since it can characterize the structures of materials, compared to the effects of stimulus energy taxes.
